title: A case of heterotopic heart transplant as a "biologic left ventricular assist" in restrictive cardiomyopathy.
abstract: Heterotopic heart transplant (HHT) has traditionally been thought of as creating 2 parallel circulations. We present a case of using the donor heart as a "biologic left ventricular assist" (bio-LVA). The heterotopic technique used consisted of 4 anastomoses: the donor heart pulmonary artery (PA) to the native heart right atrium, the superior vena cava to superior vena cava, the left atrium to left atrium, and the aorta to aorta. A 9-year-old boy with restrictive cardiomyopathy, a PA pressure of 85/53 mmHg, received a HHT because he would probably not be able to tolerate an orthotopic heart transplant secondary to elevated PA pressure. He is currently alive 14 years post-transplantation.
